Future Trends of Automobile Steering System

Automobile Steering System:

Automobile steering is one of most necessary system of any automobile. This is getting better and more better during the years and technological advances. We have already seen some basic automobile steering system like below:

1. Manual Steering System.
2. Power Assisted Steering System.
3. Electro-Hydraulic Steering System.

Below I have discussed some future technological systems related to automobile steering.

1. Magna-steering systems:

In this system, steering of automobile is achieved through steering gear rotary valve, with a magnetically controlled variable rate torsion bar. This system have some unique advantages, apart from old systems.

Advantages Magna-steering systems:

1. This design is very flexible and can be accommodate as per need and space availability.
2. It employs the non-contact mechanism. i.e. no mechanical parts contact with each other which reduces the chances of friction between them and hence wear and tear of parts.
3. Non-contact mechanism have one more advantage. It reduces the insertion of backlash in the system performance.
4. System includes less moving parts and hence better and long life performance.
5. This system can be integrated with computer and it can be tuned as per need of driver and ride. This phenomenon is called as the laptop tuning of the system.

2. Four wheel steering (Quadra-steering) System:

As name suggests, it includes steering with 4 wheels. i.e. all 4 wheels turn in unison to get optimum turning. This system is simple to visualize but hard to design and employ in the practical.This system is also called as Zero Turning Radius.

Advantages of Four Wheel Steering:

1. This system improves the vehicle performance and stability at higher speeds.
2. Increases stability in lane change maneuvers.
3. Increased maneuverability while driving/tugging trailers at low speeds.
4. Turning circle diameter is significantly reduced.

3. Steer By Wire System (SBW):

Advantages:

1. This system eliminates the hydraulic fluid.
2. Much hardware is reduced here which is definitely good for mechanical system.
3. It integrates front as well as rear wheels which gives steering capability to front as well rear wheels.
4. Electrical interface for system generation.

These are various Future Trends of Automobile Steering System.
